nuinrrtacure of mor-'iur 'forming meterial and the recovery el the distillation l5 products of the oilshele coultl he carriecl out in one process. '.lhis is the more surpris 1g hy the evaporation oi' the distillzihle prooi ucts from shale only zi part ot he energy presentv in the oilshale is employed for heat- 20 ing0 purposes. @ne Should expect that any loss of ineterial having heating value shoulfl he. avoided, when oilshale is burned with milled liniestone, to' obtain a ruw i'iuil'eriel for mortar, But this is not the inet.

According izo this invention the oilshele nuxetl wiih limestone, inurl, etc. hurn't in a convenient npijora'tus allowingdistillation azul recovery of the distillation iliroilucts. At the saine time also other Ytuels` having 3C' relatively e. very little value can he zultletl, for example Slack, breeze :nul similar fuel wastes. The use ot such other -fuels (fuif take place in any ilesiretl measure.` The .special 'feature of lliis invention is the Uhli- 35 lion of he. t elisorliine materiels to the. fuel.y used 'for lhe inanuizutnre of eleani. Special nuiteriels, strongly absorbing hea@ es li1ne stone or .um "i, which h v their decomposition lower the temperature. are employed. rThe 4l) amount of ethnixture is liest chosen so, that no sinei" takes place. By avoiding sinlering of ne shale residues itv is possjole lo ohtein a valuable raw niateriul ifor i'nortar.

The residu-es :ire worltetl either directly. 45 by millingl evenually alter an eflilition or other materiels unil e seco-ntl burning, or the hurnt shale seperated. from the residue is useil Y.for the manufacture ot' cenient according to well known processes.

The residues are furthermore very gooil fniaterial for the i'x'ianul'avcture oi artilicial stores.
